Elongate and of even breadth, rather narrow and somev^hat flatly de- 

 pressed, not unlike a medium .sized H. elongatula , but of more even breadth, 

 with broader head and more robust antennae, of which the next-last joints 

 are distinctly transverse. Furthermore, debilis and also the following 

 species are distinguished by, that the tip of the mesosternum is peculi-.

 tennae, mouth-parts and legs reddish yellow. 



Head, pronotum and elytra extremely finely shagreened at surface, and 

 therefore rather feebly or dully glistening; the head proportionately 

 large, about as broad as pronotum, very finely or indistinctly punctated; 

 antennae somewhat longer than head and pronotum together, rather slender,

 somewhat thickened distally, their third joint a little shorter than the 

 second, the fourth longer than broad, the fifth and sixth as long as broad, 

 the following (7-lC) feebly increasingly transverse, so that the next-

 ytra, hardly ''/j broader than long, distinctly narrowing posteriorly, with
